Definitions

  • the subject matter of the invention is an embroidery module for a free-arm sewing machine.
  • Free-arm sewing machines for home use have a relatively small work surface, in order also to be able to process tubular work pieces, such as sleeves, etc.
  • tubular work pieces such as sleeves, etc.
  • slide-on extension tables which have a U-shaped configuration and which enclose the free arm on three sides, are frequently supplied with the sewing machine. This significantly larger work and support surface, however, prevents the sewing or embroidering of tubular sewing material.
  • the work surface can also be expanded for large work pieces by docking an embroidery module, which is used for driving and supporting an embroidery hoop.
  • an embroidery module which is used for driving and supporting an embroidery hoop.
  • the slide-on extension table or the embroidery module must be removed again, in order to be able to perform different work on the sewing machine.
  • One objective of the present invention is to create an embroidery module, which can be used both for its main purpose, namely the driving and guiding of an embroidery hoop, but also continuously as an enlarged work surface, without having to limit the possibilities of the free-arm sewing or free-arm embroidery for tubular work pieces when the embroidery module is docked.
  • the configuration of the embroidery module according to the invention is achieved without issue in various respects by the configuration of the embroidery module according to the invention.
  • the embroidery module is used as an expanded work surface advantageous thanks to the embroidery hoop support that can be completely removed from the embroidery module, but also an embroidery hoop support for larger embroidery hoops, which is consequently long due to the large edge length of such embroidery hoops, can be stored separately from the embroidery module.
  • the embroidery module can always remain coupled to the sewing machine without the embroidery hoop support or it is advantageous to keep this module docked to the machine.
  • the embroidery module can also remain docked.
  • the latter construction can be removed from the machine when only tubular work pieces are to be processed for a long time, in contrast to embroidery hoop drives connected permanently to the machine.
  • the mounting of the embroidery hoop support in guides, which are located at the sides of the embroidery module prevents dust or sewing instruments, e.g., needles or cut threads, from reaching into the guide rails.
  • the slot-free surface of the embroidery module forms a closed material support that does not interfere with the movement of the material when sewing or embroidering.
  • FIG. 1 is a perspective view of an embroidery module with the embroidery hoop support removed;
  • FIG. 2 is a perspective bottom view of an embroidery module with the embroidery hoop support removed;
  • FIG. 3 a is a perspective view of a sewing machine with docked embroidery module
  • FIG. 3 b is a side view of the sewing machine with docked embroidery module
  • FIG. 3 c is a top view of a sewing machine with docked embroidery module
  • FIG. 4 a is a perspective view of the sewing machine with docked embroidery module and coupled slide-on extension table
  • FIG. 4 b is a side view of the sewing machine with coupled slide-on extension table
  • FIG. 4 c is a top view of a sewing machine with coupled slide-on extension table
  • FIG. 5 a is a perspective view of the sewing machine and the embroidery module with coupled embroidery hoop support, as well as the embroidery hoop and the slide-on extension table;
  • FIG. 5 b is a side view of the sewing machine and the embroidery module with coupled embroidery hoop support, as well as embroidery hoop with slide-on extension table;
  • FIG. 5 c is a top view of a sewing machine and the embroidery module with coupled embroidery hoop support, as well as embroidery hoop with slide-on extension table;
  • FIG. 6 a is a perspective view of the sewing machine, the embroidery module, and coupled embroidery hoop support without slide-on extension table;
  • FIG. 6 b is a side view of the sewing machine, the embroidery module, and coupled embroidery hoop support without slide-on extension table;
  • FIG. 6 c is a top view of a sewing machine and the embroidery module with coupled embroidery hoop support without slide-on extension table.
  • the embroidery module 1 shown in FIGS. 1 and 2 includes a main body 3 with an essentially rectangular outline.
  • a recess 5 which can be open at the bottom or can have an approximately v-shaped or cylindrical shell-shaped base 7 , as in the shown configuration, is visible on one of the two narrow sides.
  • a base plate 9 Underneath the base 7 , a base plate 9 extending over the entire main body 3 can be attached.
  • slots 11 extending on the side of the narrow-side recess 5 up to or only approximately up to the end of the embroidery module 1 are formed parallel to its upper surface. In contrast, on the opposite narrow side, they are open.
  • drives such as toothed belts, round belts, metal bands, cords, or shafts, which can transport an embroidery hoop support 13 guided in the X-direction exactly parallel through the use of suitable couplings.
  • the drives for the embroidery hoop support 13 which are not shown in the figures, because they are not visible, are driven by at least one first electric motor inserted within the embroidery module 1 .
  • the embroidery hoop support 13 is connected to a transport device located behind the slots 11 by brackets 15 (cf. FIG. 2 ), which engage through the slots 11 into the not-described and not-visible couplings.
  • the brackets 15 are dimensioned so that an intermediate space exists between the elongated housing 17 of the embroidery hoop support 13 and the work surface 19 on the embroidery module 1 . That is, the embroidery hoop support 13 or the embroidery hoop 25 does not contact the surface of the embroidery module 1 .
  • a second drive motor for an embroidery hoop adapter 21 is provided, which is mounted so that it can move in the Y-direction in the embroidery hoop support 13 , in the cylindrical section 20 in the center in FIGS. 1 and 2 .
  • the embroidery hoop adapter 21 can have, for example, bores 23 , in which an embroidery hoop 25 can be fixed (cf. FIGS. 5 and 6 ).
  • the embroidery module 1 is described in more detail in combination with a household sewing machine 27 , i.e., docked to such a machine.
  • FIGS. 3 a to 3 c it can be seen that the embroidery module 1 is fixed at the end along the edge Q to the end surface of the base plate 29 of the sewing machine 27 and that the free arm 31 projects only by a small amount a into the recess 5 on the embroidery module 1 .
  • the other area of the recess 5 in the embroidery module 1 is not filled by a part of the sewing machine 27 , but instead is used as a free space 33 for inserting, e.g., tubular sewing material over the free arm 31 .
  • the embroidery module 1 is used solely as an enlarged work surface, i.e., as a sewing-material support especially when sewing large surface area work pieces.
  • a slide-on extension table 35 can be attached, which can also be docked to the free arm 31 of the sewing machine without an embroidery module 1 . Therefore, on one hand the free space 33 formed by the recess 5 is closed at the top and on the other hand the contact surface on the sewing machine is further expanded (cf. FIGS. 4 a to 4 c ) in front of and behind the free arm 31 (viewed in the direction of sewing). In this arrangement, it is obvious that the processing of tubular work pieces is not possible.
  • the embroidery hoop support 13 is placed on the embroidery module 1 . This is supported by the two brackets 15 , which engage in the side slots 11 on the foundation 3 of the embroidery module 1 .
  • the embroidery hoop 25 is fixed on the embroidery hoop support 13 , with which sewing material 37 held in tension on the hoop is mounted so that it can move via a computer-assisted program under the needle (not shown) of the sewing machine 27 in the x-direction and the y-direction.
  • the embroidery hoop 25 here lies on the slide-on extension table 35 , as is shown in FIGS. 4 a to 4 c.
  • the embroidery hoop 25 lies directly on the surface of the free arm 31 . That is, the free space 33 , formed by the recess 5 , is not closed at the top and the free arm 31 itself is free at the side. Consequently, tubular work pieces or also hemispherical work pieces, such as caps, can also be tensioned in the embroidery hoop 25 .
  • the non-tensioned part of this sewing material can move without interference around the free arm 31 during the sewing or embroidering.
  • the module does not have to be removed from the sewing machine 27 . Consequently, all of the work performed on a sewing machine 27 can also be performed when the embroidery module 1 remains docked. A lot of sewing work, in which the embroidery module 1 is not needed, can benefit from this module, however, when it is docked for sewing, quilting, or embroidery.
  • the embroidery hoop support 13 which is not needed for work without the embroidery hoop 25 , can be removed easily from the embroidery module 1 without a tool and placed to the side.
